BACKGROUND

The present disclosure relates to the field of communication technology,and especially to a display method and a display device.

A portable device in the prior art includes an input device or acorresponding input region. Thus, the size of the display region fordisplaying output content is smaller than that of the maximum displayregion supported by the portable device.

DETAILED DESCRIPTION

A display method and a display device are provided respectively, in thefollowing embodiments of the present disclosure.

In order to make the technical solutions of the embodiments of thepresent disclosure better understood by those skilled in the art, and tomake the above objects, features and advantages of the embodiments ofthe present disclosure more apparent, a further detailed descriptionwill be made to the technical solutions of the embodiments of thepresent disclosure with reference to the drawings.

Referring to FIG. 1, it is a flowchart showing a display methodaccording to a first embodiment of the present disclosure, which isapplied to a first device including a display module and a first inputmodule, the first device having at least a first state in which it isconnected to a second device including a second input module, thedisplay module displays output content of the first device in the firststate and is capable of receiving input from the second input module,and a second state in which it is disconnected with the second device,the display module displays the output content of the first device andis capable of receiving input from the first input module. The flow ofthis embodiment is as follows.

At Step 101, a first output content of the first device is displayed ina first region of the display module by the first device, when the firstdevice is in the first state.

In the present embodiment, the first device may be a tablet, a smart TVor a cell phone. The display module may be a LCD display, a LED displayetc. The first state is a connected state. Thus, the first device may beconnected to a second device which may be a keyboard in particular, andthe second input module is a key. Alternatively, the second device maybe a dock including a keyboard, and the second input module is a key ora cursor control module such as a pointer or a touch pad. In the firststate, the first device receives input from the second input module ofthe second device, and displays the first output content of the firstdevice.

For example, when the first device is a tablet computer (a PAD device),which may be connected to a keyboard in the first state, at this time,the PAD device may receive input from the keyboard, and the first outputcontent of the operating system (“OS”) of the PAD device is displayedthrough the first region the size of which is consistent with the sizeof the display module.

At Step 102, it is detected that the first device enters the secondstate from the first state.

The first device has an interface for connecting to the second device.The first device has an interface detection module which may detect theplug state of the interface to decide whether the first device is in thefirst state in which the first device is connected to the second device,or in the second state in which the first device is disconnected withthe second device. For example, the PAD device has a universal serialbus (“USB”) interface. When the PAD is connected to a peripheralkeyboard, it is detected that the PAD device enters the first state.When the keyboard connected to the USB interface is detached, it isdetected that the PAD device enters the second state.

At Step 103, the first device displays the first output content in thesecond region of the display module, and displays the second outputcontent in the third region of the display module.

The first output content is different from the second output content,the second region is not overlapped with the third region, and the firstregion contains the second region and the third region. That is, afterthe first device enters the second state from the first state, thesystem output is the first output content. That is, the output contentof the system remains unchanged. However, the first output content isdisplayed through the first region in the first state, and is displayedthrough the second region smaller than the first region in the secondstate by the first device. That is, the region for displaying the firstoutput content is reduced while the region for displaying other contentis increased. That is, a third region for displaying the second outputcontent is increased.

Further, the first input module may include a touch sensitive module,which is arranged to be overlapped with at least the third region of thedisplay module, and is operable to sense a touch operation on the firstoutput content by an operating object. When the first device is in thefirst state, input may be made through the connected second device, suchas the keyboard, or may be made in combination with the first inputmodule. When the first device is in the second state, touch input ismade only through the touch sensitive module. For example, the touchinput may be made on the touch sensitive module at least correspondingto the third region, which may be arranged in maximum to be overlappedwith the first region. In the second state, still assume that the firstdevice is the PAD device. When the PAD device is used alone, the touchinput operation is carried out through the touch sensitive module. Thesecond region for displaying the first output content of the OS on thedisplay module is smaller than the first region in the first state. And,the third region may function as the touch gesture input area fordisplaying the touch input range or the touch input instructionidentifier.

In particular, when the second output content is an operationinstruction identifier, it is used to trigger a command corresponding tothe operation instruction identifier when it is detected that a touchsensitive region corresponding to the operation instruction identifiersenses an operation by the operating object. The operation instructionidentifier includes a fixed operation instruction identifier, forexample, a home button, a back button, etc., which is displayed bydefault when the first device enters the second state. Alternatively,the operation instruction identifier includes an instruction identifierassociated with the first output content. For example, the OS of thefirst device performs a song playing application to display a player inthe first region including a playlist, a play process and play controlinformation etc., when a song is played by the player. When the firstdevices enters the second state, it is still displayed in the secondregion that the song is played by the player, and the instructionidentifier corresponding to the player is displayed in the third region,which may include a “next song” instruction identifier, a “previoussong” instruction identifier, a “volume adjustment” instructionidentifier, etc. When it is detected that the “next song” instructionidentifier is clicked by the operating object, the command for playingthe next song corresponding to the instruction identifier is obtained toperform the command, so that the player in the first output contentjumps to the next song in the playlist to play it. It can be seen thatwhen the second output content is displayed in the third region of thedisplay module, the second output content associated with the firstoutput content may be determined based on the first output content, andthe second output content is displayed in the third region of thedisplay module. That is, the second output content is associated withthe first output content. When the first output content is changed, thesecond output content is the operation instruction identifiercorresponding to the changed first output content. For example, when thefirst output content is the player, the second output contentcorresponds to the operation instruction identifier for playing audio orvideo. When the first output content is a game, the second outputcontent corresponds to the operation instruction identifier of the game.

Alternatively, the second output content may include range informationon touch operation region for prompting that a touch operation on thefirst output content can be made in the region limited by the rangeinformation. For example, the range of the operation region may beprompted to the user by displaying with a filled-in color different fromthe first output content, for example, displaying black color. When aslide gesture is detected in the range of the operation region, thecommand corresponding to the slide gesture is performed. Further, it isenough to detect that there is the touch operation in the region, and itis not necessary to limit the location of the touch operation. Forexample, when the operation for sliding leftward is performed, no matterwhere the starting point of the sliding is located in the region, thecommand corresponding to the sliding leftward operation is generated aslong as the operation for sliding leftward is detected. In addition, thecommand corresponding to the sliding operation may be a system levelcommand. That is, no matter whatever the first output content is, thesame command is issued. For example, uniformly, the sliding leftwardoperation corresponds to the backward command, the sliding rightwardoperation corresponds to the task manager command, the double clickoperation corresponds to the main menu invoking command, etc. Of course,similar to the above described embodiment, when the first output contentis different, the same touch input gesture may correspond to differentcommands, which is not limited in the embodiments of the presentdisclosure.

In addition, when the first device is a portable device such as a tabletor a cell phone, since it is of a small size and is convenient for theuser to be carried by hand, it has multiple holding manners. That is,the device is rotatable. The rotating direction may be a slidingdirection with respect to the device, or may be a sliding direction withrespect to the space. For example, with respect to the device, theleftward sliding to the space (leftward sliding to the device)represents backward operation when the device is used vertically, thedownward sliding to the space (leftward sliding to the device)represents backward operation when the device is used horizontally. Withrespect to the space, the leftward sliding to the space (leftwardsliding to the device) represents backward operation when the device isused vertically, and the leftward sliding to the space (upward slidingto the device) represents backward operation when the device is usedhorizontally. It can be seen that it should be determined with respectto the space, so that the sliding gesture with respect to the device andthe corresponding command are switched when the leftward slidingcorresponds to the same operation.

Further, the display module further includes a fourth region in thesecond state. The first region includes the second region, the thirdregion and the fourth region which do not overlap with each other. In anembodiment, the sum of the areas of the second region, the third regionand the fourth region in the second state is consistent with that of thefirst region in the first state. The touch sensitive module isoverlapped with the first region of the display module in the firststate, and is operable to sense a touch operation on the first outputcontent by the operating object. That is, when the first device is a PADdevice, although it may perform input operation by connecting akeyboard, the screen of its own still has a touch input function. In thesecond state, the touch sensitive module includes a second touchsensitive region corresponding to the second region, a third touchsensitive region corresponding to the third region and a fourthsensitive region corresponding to the fourth region in the second state,the first device responds to touch operation in the second touchsensitive region and the third touch sensitive region by the operatingobject, and does not respond to touch operation in the fourth touchsensitive region by the operating object. That is, the fourth touchsensitive region corresponding to the fourth region is an invalid touchregion, to further reduce the area of the second region for displayingthe first output content when the PAD device is used alone to beconvenient for the user to operate. The range information on the displayregion may be displayed in the fourth region. For example, it isprompted which region is an invalid touch region for the touch operationby a special display color or a display frame. Further, for a betterappearance, the logo information of the product may be displayed in thefourth region.

It is to be noted that the display module may do not include the fourthregion as well, but the touch sensitive module includes a fourth touchsensitive region which does not overlap with the second touch sensitiveregion and the third touch sensitive region, and which does not respondto the touch input operation, either.

The display process of the first device entering the second state fromthe first state has been described in the above embodiment. Similarly,the display process of the first device entering the first state fromthe second state includes: displaying a first output content in a secondregion of the display module by the first device, and displaying thesecond output content in the third region of the display module, whenthe first device is in the second state; displaying the first outputcontent of the first device in a first region of the display module bythe first device, when it is detected that the first device enters thefirst state from the second state; wherein the first output content isdifferent from the second output content, the second region is notoverlapped with the third region, and the first region contains thesecond region and the third region.

Referring to FIG. 2, it is a flowchart of a display method according toa second embodiment of the present disclosure, which is applied to afirst device including a display module and a first input module, thefirst device having at least a first state in which it is connected to asecond device including a second input module, the display moduledisplays a third output content of the second device in the first state,and is capable of receiving input of the second input module, and asecond state in which it is disconnected with the second device, thedisplay module displays a first output content of the first device andis capable of receiving input from the first input module. The flowchartof the method in this embodiment is as follows.

At Step S201, the third output content of the second device is displayedin a first region of the display module by the first device, when thefirst device is in the first state.

In the present embodiment, the first device may be a tablet, a smart TVor a cell phone. The display module may be a LCD display, a LED displayetc. The first device may have a first OS working independently. Thefirst state is a connected state. Thus, the first device may beconnected to a second device which is a device including a second OSworking independently, for example, a desktop PC, a notebook computer, acell phone, a tablet computer. The second input module may be a buttonor a cursor control module, for example, a pointer or a touch pad etc.Since the first device and the second device have their own independentOSs, the first device displays the third output content of the seconddevice when the first device receives the input of the second inputmodule of the second device in the first state.

The embodiment of the present disclosure may be applied in a hybridsystem consisted of the first device and the second device, wherein thehybrid system may be combined by two independent devices, or may includeone portable terminal of the first device and the second device. Forexample, the hybrid system may be consisted of a notebook computer witha single system and a smart phone, or may be consisted of a notebookcomputer with a hybrid system architecture.

The first device may include a first hardware system, for example aslave system based on an X86 architecture or an ARM architectureprocessor. The second device may include a second hardware system, forexample a master system based on an X86 architecture or an ARMarchitecture processor. That is, the first system and the second systemmay be based on the same hardware architecture, or may be based ondifferent hardware architectures. In addition, the master system and theslave system may be distinguished based on the importance, the priority,the processing capability or the power consumption. For example, themaster system is of a high importance, high priority, powerfulprocessing capability or high power consumption, while the slave systemis opposite to that. Alternatively, the different names may be just fordistinguishing, but not limit the importance, the priority, theprocessing capability or the power consumption of the system.

Further, the second device may include a second hardware system having asecond OS, for example a second hardware system installed with a desktopdevice OS (e.g., Windows 7, Linux or MacOS) or installed with a portabledevice OS (e.g., Android, Symbian or iOS). The first device may includea first hardware system having a first OS, for example a first hardwaresystem installed with a desktop device OS (e.g., Windows 7, Linux orMacOS) or installed with a portable device OS (e.g., Android, Symbian oriOS). That is, the first OS and the second OS may be the same or may bedifferent, as long as they may run the corresponding hardware system.Optionally, the second device is a master system which is based on theX86 architecture processor and installed with a desktop OS. The firstdevice is a slave system which is based on the ARM architectureprocessor and installed with a portable device OS.

The first device has a first interface, the second device has a secondinterface, and the first device and the second device are connected ordisconnected through the first interface and the second interface. Thefirst interface and the second interface may be a wire interface or awireless interface, which is not limited here, as long as the firstinterface of the first device and the second interface of the seconddevice may connect and disconnect the two devices and may communicatethe system state information.

When the first interface and the second interface are wire interfaces,the first interface may be a USB interface or a UART interface, or acustom interface to enable the connection or disconnection between thetwo devices. The second interface may also be a corresponding USBinterface or a UART interface, or a custom interface to enable theconnection or disconnection between the two devices. When the firstinterface and the second interface are wireless interfaces, they may bematched Bluetooth interfaces, infrared ray interfaces, or WiFiinterfaces.

Taking the notebook with a hybrid system architecture as an example, thefirst device and the second device are two independent systems which maywork independently or cooperatively. The second device is arranged atthe main unit (main case, host) side with respect to the single systemnotebook, and includes a processing device, an input device and nodisplay device. The first device is arranged at the display side withrespect to the single system notebook, and includes a processing device,an input device and a display device. When the first device and thesecond device combine to work, they may share some hardware devices,such as the display device. Since the display device is integrated withthe first device, it is only provided to the first device when the firstdevice and the second device are disconnected, and may be provided tothe first device or the second device when the first device and thesecond device are connected. That is, the running result/output contentof the first device and/or the second device may be displayed throughthe display device.

That is, in the portable device having a hybrid system architecture, thetablet computer having a slave system is equivalent to the first devicein the embodiment of the present disclosure, and the main unit having amaster system is equivalent to the second device in the embodiment ofthe present disclosure.

In particular, taking an example in which the first device is a tablecomputer having a slave OS and the second device is a main unit having amaster OS and includes a keyboard, the PAD device and the master devicecomposes the dual system device in the first state, wherein the firstdevice may be referred to the slave device of the dual system, and thesecond device is referred to the master device of the dual system. Atthis time, the PAD system may function as the display section whichdisplays a third output content of the master OS of the master device inthe dual system device. The third output content is displayed in thefirst region the size of which is consistent with that of the displaymodule.

At Step S202, it is detected that the first device enters the secondstate from the first state.

The first device has an interface for connecting the second device, andhas an interface detection module for detecting the plug state of theinterface to decide whether the first device is in the first state inwhich the first device is connected with the second device, or thesecond state in which the first device is disconnected with the seconddevice. For example, the PAD device has a USB interface. When the PADdevice and the main case are connected, it is detected that the PADdevice enters the first state. When the main case connected to the USBinterface is plug off, it is detected that the PAD device enters thesecond state.

At Step S203, the first device displays the first output content in asecond region of the display module, and displays a second outputcontent of the first device in a third region of the display module.

The first output content is different from the second output content,the second region is not overlapped with the third region, and the firstregion contains the second region and the third region. In the presentembodiment, after the first device enters the second state from thefirst state, the system output content is changed from the third outputcontent of the second device to the first output content of the firstdevice. That is, the system output content is changed. Since the firstdevice and the second device may be of the same hardware system andsoftware system, the first output content and the third output contentmay be the same when the software environment is the same (the same OS,the same software application). That is, when the first device and thesecond device are separated, the second device acquires the operationparameter according to its operation environment and transmits it to thefirst device. The first device recovers the operation environmentaccording to the operation parameter. Of course, the first outputcontent and the third output content come from different devices andthey may not be the same.

In addition to the change to the output content, the first devicedisplays the third output content of the second device through its firstregion in the first state, and displays the first output content of thefirst device through the second region smaller than the first region inthe second state. In the second state, the first device increases itsregion for displaying other content, i.e., increases the third regionfor displaying the second output content, while decreasing the regionfor displaying the first output content.

Taking the example in which the first device is a PAD device, when thePAD device is used alone, the PAD device displays the first outputcontent of the slave OS of the slave device in the dual system device.When the PAD device is used in combination with the main case, itdisplays the third output content of the master OS of the master deviceof the dual system device. That is, the output content displayed whenPAD device and the main case are combined together is different from theoutput content displayed when the PAD device is used alone.

Further, the first input module may include a touch sensitive module.The touch sensitive module is arranged to be overlapped with at leastthe third region of the display module, and is operable to sense a touchoperation on the first output content by an operating object. When thefirst device is in the first state, the display module displays thethird output content output by the second device. The second device maybe performed by the second input module included in the second device,for example, the keyboard, directly. The second device responds to theinput of the second input module, and changes its output content.Alternatively, the input may be done by using the first input module incooperation. That is, the input of the first input module is transmittedto the second device. The second device responds to the input from thefirst input module and changes its output content. When the first deviceis in the second state, the touch input may be done only by the touchsensitive module. For example, the touch input is done at least by thetouch sensitive module corresponding to the third region, which isoverlapped with the first region in maximum. In the second state, stillassuming that the first device is a PAD device, the touch inputoperation is performed by the touch sensitive module when the PAD deviceis used alone. The second region for displaying the first output contentof the OS on the display module is smaller than the first region in thefirst state. The third region may be used as the touch gesture inputarea for displaying the touch input range or the touch input instructionidentifier.

In particular, when the second output content is an operationinstruction identifier, it is used to trigger a command corresponding tothe operation instruction identifier when it is detected that a touchsensitive region corresponding to the operation instruction identifiersenses an operation by the operating object. The operation instructionidentifier includes a fixed operation instruction identifier, forexample, a home button, a back button, etc., which is displayed bydefault when the first device enters the second state. Alternatively,the operation instruction identifier includes an instruction identifierassociated with the first output content. For example, the OS of thefirst device performs a song playing application to display a player inthe first region including a playlist, a play process and play controlinformation etc., when a song is played by the player. When the firstdevices enters the second state, it is still displayed in the secondregion that the song is played by the player, and the instructionidentifier corresponding to the player is displayed in the third region,which may include a “next song” instruction identifier, a “previoussong” instruction identifier, a “volume adjustment” instructionidentifier, etc. When it is detected that the “next song” instructionidentifier is clicked by the operating object, the command for playingthe next song corresponding to the instruction identifier is obtained toperform the command, so that the player in the first output contentjumps to the next song in the playlist to play it. It can be seen thatwhen the second output content is displayed in the third region of thedisplay module, the second output content associated with the firstoutput content may be determined based on the first output content, andthe second output content is displayed in the third region of thedisplay module. That is, the second output content is associated withthe first output content. When the first output content is changed, thesecond output content is the operation instruction identifiercorresponding to the changed first output content. For example, when thefirst output content is the player, the second output contentcorresponds to the operation instruction identifier for playing audio orvideo. When the first output content is a game, the second outputcontent corresponds to the operation instruction identifier of the game.

Alternatively, the second output content may include range informationon touch operation region for prompting that a touch operation on thefirst output content can be made in the region limited by the rangeinformation. For example, the range of the operation region may beprompted to the user by displaying with a filled-in color different fromthe first output content, for example, displaying black color. When aslide gesture is detected in the range of the operation region, thecommand corresponding to the slide gesture is performed. Further, it isenough to detect that there is the touch operation in the region, and itis not necessary to limit the location of the touch operation. Forexample, when the operation for sliding leftward is performed, no matterwhere the starting point of the sliding is located in the region, thecommand corresponding to the sliding leftward operation is generated aslong as the operation for sliding leftward is detected. In addition, thecommand corresponding to the sliding operation may be a system levelcommand. That is, no matter whatever the first output content is, thesame command is issued. For example, uniformly, the sliding leftwardoperation corresponds to the back command, the sliding rightwardoperation corresponds to the task manager command, the double clickoperation corresponds to the main menu invoking command, etc. Of course,similar to the above described embodiment, when the first output contentis different, the same touch input gesture may correspond to differentcommands, which is not limited in the embodiments of the presentdisclosure.

In addition, when the first device is a portable device such as a tabletor a cell phone, since it is of a small size and is convenient for theuser to be carried by hand, it has multiple holding manners. That is,the device is rotatable. The rotating direction may be a slidingdirection with respect to the device, or may be a sliding direction withrespect to the space. For example, with respect to the device, theleftward sliding to the space (leftward sliding to the device)represents backward operation when the device is used vertically, thedownward sliding to the space (leftward sliding to the device)represents backward operation when the device is used horizontally. Withrespect to the space, the leftward sliding to the space (leftwardsliding to the device) represents backward operation when the device isused vertically, and the leftward sliding to the space (upward slidingto the device) represents backward operation when the device is usedhorizontally. It can be seen that it may be determined with respect tothe space, so that the sliding gesture with respect to the device andthe corresponding command are switched when the leftward slidingcorresponds to the same operation.

Further, the display module further includes a fourth region in thesecond state. The first region includes the second region, the thirdregion and the fourth region which do not overlap with each other. In anembodiment, the sum of the areas of the second region, the third regionand the fourth region in the second state is consistent with that of thefirst region in the first state. The touch sensitive module isoverlapped with the first region of the display module in the firststate, and is operable to sense a touch operation on the third outputcontent by an operating object. That is, when the first device is a PADdevice, although it may perform input operation by connecting akeyboard, the screen of its own still has a touch input function. In thesecond state, the touch sensitive module includes a second touchsensitive region corresponding to the second region, a third touchsensitive region corresponding to the third region and a fourthsensitive region corresponding to the fourth region in the second state,the first device responds to touch operation in the second touchsensitive region and the third touch sensitive region by the operatingobject, and does not respond to touch operation in the fourth touchsensitive region by the operating object. That is, the fourth touchsensitive region corresponding to the fourth region is an invalid touchregion, to further reduce the area of the second region for displayingthe first output content when the PAD device is used alone to beconvenient for the user to operate. The range information on the displayregion may be displayed in the fourth region. For example, it isprompted which region is the invalid touch region for the touchoperation by a special display color or a display frame. Further, for abetter appearance, the logo information of the product may be displayedin the fourth region.

It is to be noted that the display module may do not include the fourthregion as well, but the touch sensitive module includes a fourth touchsensitive region which does not overlap with the second touch sensitiveregion and the third touch sensitive region, and which does not respondto the touch input operation, either.

The display process of the first device entering the second state fromthe first state has been described in the above embodiment. Similarly,the display process of the first device entering the first state fromthe second state includes: displaying a first output content of thefirst device in a second region of the display module by the firstdevice, and displaying the second output content in the third region ofthe display module when the first device is in the second state;displaying the third output content of the second device in a firstregion of the display module by the first device, when it is detectedthat the first device enters the first state from the second state;wherein the first output content is different from the second outputcontent, the second region is not overlapped with the third region, andthe first region contains the second region and the third region.

Referring to FIG. 3, it is a structural schematic diagram showing a dualsystem device which may be formed by the first device and the seconddevice combining together.

The first device and the second device may be combined into a dualsystem device to use. Assume that the first device is a PAD devicehaving a touch input function, the second device is a main unit having akeyboard. It can be known from the description of the above embodimentthat the plug state between the master device and the slave device isdetected by the state detection module. That is, the state detectionmodule may detect the slave device is in the first state in which it isconnected to the master device, or the second state in which it isseparated from the master device. When it is in the first state, theswitch module is controlled to switch to display the third outputcontent of the master system through the first region of the displaymodule. When it is in the second state, the switch module is controlledto switch to display the first output content of the slave systemthrough the second region of the display module. The regiondistinguishing of the display module in different states and therelationships between the regions are consistent with those described inthe above embodiment, and are not described here to avoid redundancy.

Referring to FIG. 4, it is a schematic diagram of a display region of aPAD device in the first state.

It can be known from FIG. 4A that the size of the first display regionof the PAD device is consistent with that of the whole display module.

Referring to FIG. 4B, it is a schematic diagram of a display region of aPAD device in the second state.

It can be known from FIG. 4B that the display module of the PAD deviceincludes the second region, the third region and the fourth region inthe second state. The dashed line shown in FIG. 4B is to distinguish theboundary between the third region and the fourth region, which is notvisible in the real application. The content displayed in the individualregion is as described in the above embodiment, and will not bedescribed here to avoid redundancy.

It can be known from FIGS. 4A and 4B that the first device in theembodiment of the present disclosure may display the third outputcontent through the first region of the display module in the firststate, and may display the first output content through the secondregion of the display module in the second state. When the first deviceis used alone, the region for displaying the first output content issmaller than the region for displaying the third output content when thefirst device is connected to the second device, especially when thefirst device is a PAD device. Thereby, the user requirement for thescreen display when the two systems are combined is met, and the userexperience is improved.
